Which of the following amines will not give N2 gas on treatment with nitrous acid (NaNO2 + HCl)?
C2H5NH2
CH3NH2
(CH3)2CH-NH2
All will give N2
D.
All will give N2
All aliphatic primary amines liberate N2 gas on treatment with HNO2.
R - NH2 + HONO R-OH + N2 + H2O
Since no other class of amines liberate N2 gas on treatment with HNO2 , this reaction is used as a test for aliphatic primary amines.
The reaction
is called
Claisen-Schmidt reaction
Kolbe-Schmidt reaction
Schmidt reaction
Kolbe's reaction
